Study Notes

Laws and Forces for New Drivers

Key forces for drivers include gravity, inertia, momentum, kinetic and potential energy, friction, and centrifugal/centripetal forces.

Kinetic Energy

Energy an object develops while in motion; increasing speed significantly raises danger levels.
Doubling speed increases kinetic energy fourfold, resulting in quadrupled braking distances.

Gravity

The Earth's attraction force affects vehicle handling, especially when downhill.
A vehicle's acceleration increases with gravity, potentially causing excessive speed.

Managing Driving Downhill

Shift to a lower gear or gently apply brakes to maintain control and speed.

Preventing Parked Cars from Rolling

Keep the car in low gear or 'Park' for automatics, apply the parking brake, and position front wheels to prevent rolling.
Turn wheels toward the curb when parked downhill, and away when uphill. Use a brick as extra safety on inclines.

Newton's Law of Inertia

An object at rest will stay at rest, and an object in motion continues in motion unless acted on by an unbalanced force.

Importance of Seat Belts

Seat belts prevent occupants from moving forward during sudden stops by providing necessary resistance.
Loose objects in the vehicle can become projectiles, causing injury during sudden stops — store them in the trunk.

Potential Energy

The energy stored in an object due to its position or arrangement.

Friction

Resistance that occurs between surfaces in contact, crucial for movement and control.
Essential for starting, stopping, and turning; proper lubrication is necessary to maintain effective friction in vehicle components.

Traction

Factors affecting traction include stopping distance, centrifugal force, and hydroplaning; an increase in any can diminish traction and control over the vehicle.

Centripetal Force

The force that changes the direction of a moving object along a curved path.

Centrifugal Force

A pseudo force that appears to pull outward on a body in circular motion, increasing with acceleration; it's the reaction to centripetal force.

Laws of Motion

For every action, there is an equal and opposite reaction, fundamental to understanding movement and collisions.

Safe Cornering Guidelines

Decelerate before curves, brake gently while turning if necessary, and downshift in manual transmissions.

Force of Impact

The impact force increases with speed; higher speeds result in greater collision impact and damage.

Speed and Collision

Doubling a vehicle’s speed quadruples its force of impact in a collision.

Impact in Vehicle Collisions

In collisions between vehicles at the same speed, the lighter vehicle experiences greater impact force relative to its mass.
